    This is great! Thanks for sharing, it is a cool idea to try bringing QoL improvements from Rust to C++. Got a question:

    Does this prevent the RVO/NRVO compiler optimizations for return values? And when those fail, same question for the move-construction for types that do have a move constructor.

    Have you considered using the immediately invoked function expression (IIFE) pattern as a standards-compliant alternative to gcc statement expressions?

    Please leave that Frankenstein of a language alone. Stop bolting features on it, it's already a monster.
